摘要
The texture evolution mechanism of TA2 pure titanium under different stress conditions (tensile stress, compressive stress) was studied by tensile and compressive test methods, Schmid factor calculation, and crystal plasticity simulation calculation. Results show that in the process of tensile deformation, it is difficult to change the texture under large strains. However, in the process of compressive deformation, the texture change is significant. Under different strain paths, there are some differences in the starting deformation mode. Under different strains, with increasing the deformation, the increase in the grain number of base plane slip, conical slip, or {10 (1) over bar2} stretched twin is the main reason for the formation of different textures.
